%X In this research we try to investigate the optimum etching time for the tracks originate in (CR-39) solid state nuclear track detector after irradiated with alpha source (<sup>241</sup>Am) using three different etching techniques: the traditional method (water bath), microwaves and ultrasound devices. The track etching parameters: bulk etch rate (<em>V</em><em><sub>B</sub></em>), track etch rate (<em>V</em><em><sub>T</sub></em>), track etch rate ratio evaluates (<em>V</em>), critical angle (<em>¦È<sub>C</sub></em>), and etching efficiency (<em>¦Ç</em>) were calculated in this research. It¡¯s seen that the optimum etching time was ranging with (60 - 150 min), (20 - 30 min) and (60 - 120 min) when etching with water bath, microwave and ultrasound respectively. Also we observed that the critical angle was (24.29) when etching CR-39 detector with microwave. This value is lower than the critical angles values for the detector etched with water bath or ultrasound; thus it can be the optimum magnitude because its decrease leads to increasing the number of the tracks appeared in the detector and the etching efficiency.
